Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically to a welding fixture for automotive connecting plates. Background Technology

[0002] When processing connecting plates on automobiles, welding is required. During welding, the connecting plates need to be fixed to prevent the stress position from shifting and affecting the welding. Although current fixtures can hold rectangular connecting plates, some automobile connecting plates have irregular shapes, making it inconvenient to hold them with existing fixtures.

[0003] A search revealed a patent with publication number CN221817841U, which discloses a welding fixture for automotive connecting plates, relating to the field of fixture technology. The fixture includes a base plate, with vertical plates fixed to both ends of the top outer wall of the base plate. One vertical plate has a first electric push rod inserted at equal intervals on one side of its outer wall, and the other vertical plate has a second electric push rod inserted at equal intervals on one side of its outer wall. This invention places the connecting plate between the two vertical plates. The first and second electric push rods push pressure sensors on both sides closer together, clamping the connecting plate. When the pressure sensors abut against the side wall of the connecting plate, they transmit the detected pressure to the controller. When the pressure reaches a set value, effectively clamping and fixing the connecting plate, the controller stops pushing either the first or second electric push rod. The pressure sensors can abut at different positions on the surface of the connecting plate, facilitating the clamping of irregularly shaped connecting plates.

[0004] The existing technology can only clamp and fix irregularly shaped automotive connecting plates. However, during the welding process, the welding work of irregularly shaped connecting plates has more diverse angle requirements. Since the welding parts may be distributed on different sides and angles of the connecting plate, in order to ensure that each welding point can be welded accurately, it is often necessary to frequently change the angle of the automotive connecting plate. The existing clamps are difficult to adjust the angle of the clamped irregularly shaped connecting plates efficiently and conveniently, which affects the welding efficiency. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or existing automotive connecting plate welding fixtures, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A welding fixture for automotive connecting plates includes a frame with uprights symmetrically arranged on both sides. A second slide rail is provided inside the uprights.

[0026] Example

[0027] Please see Figures 1-4 This utility model provides a technical solution:

[0028] A welding fixture for automotive connecting plates can securely hold irregularly shaped automotive connecting plates and can conveniently and efficiently adjust their angles to meet the angle requirements of different welding parts, thereby improving welding efficiency and accuracy.

[0029] The automotive connecting plate welding fixture includes a frame 1, which is a metal frame serving as the mounting base for the device. Symmetrically arranged vertical frames 2 are circular metal frames on both sides of the frame 1. A second slide rail 11, which is a ring track, is installed inside the vertical frame 2. A second clamping member 4 and a first clamping member 3 are symmetrically slidably installed inside the vertical frame 2. Both the second clamping member 4 and the first clamping member 3 can slide along the second slide rail 11. Each of the second clamping member 4 and the first clamping member 3 includes two opposing slide seats 6 slidably mounted on the second slide rail 11. A first slide rail 5 is also provided between the two opposing slide seats 6. Each slide seat 6 includes a slide seat body 9 slidably mounted on the second slide rail 11. An adjustment handle 10 is provided on one side of the slide seat body 9 for easy manual adjustment of the slide seat 6 position. A third electromagnet 16 is provided on the other side of the slide seat body 9. The third electromagnet 16 magnetically engages with the vertical frame 2 and can fix the position of the slide seat 6 when energized.

[0030] Both the second clamping member 4 and the first clamping member 3 are slidably mounted with gripper mechanisms. Each gripper mechanism includes a slider 8 slidably mounted on one side of the first slide rail 5. The slider 8 can slide along the first slide rail 5. A pneumatic gripper 13 is inserted into and slidably mounted on one side of the slider 8. The pneumatic gripper 13 is used to grip irregularly shaped connecting plates. A drive cylinder 14 is also provided on one side of the slider 8. The drive rod of the drive cylinder 14 is connected to the pneumatic gripper 13, which can drive the pneumatic gripper 13 to extend and retract, adjusting the extension distance. A first electromagnet 7 is also provided on the slider 8. The first electromagnet 7 is magnetically engaged with the first slide rail 5, fixing the position of the slider 8 when energized. A third slide rail 12 is rotatably mounted on one side of the frame 2. The third slide rail 12 is mounted on the first clamping member 3, and a slide block 6 is inserted into and slidably mounted on the third slide rail 12. Second electromagnets 15 are provided on both sides of the second clamping member 4. The second electromagnets 15 are magnetically engaged with the third slide rail 12, achieving a rigid connection between the first clamping member 3 and the second clamping member 4 when energized.

[0031] The pneumatic gripper 13 clamps the irregularly shaped automotive connecting plate. The first electromagnet 7 and the third electromagnet 16 fix the positions of the slider 8 and the slide block 6 respectively to ensure the stability of the clamping. The drive cylinder 14 drives the pneumatic gripper 13 to extend and retract. The slider 8 slides along the first slide rail 5 and the slide block 6 slides along the second slide rail 11. The position and extension distance of the pneumatic gripper 13 can be adjusted in multiple dimensions to adapt to irregularly shaped connecting plates of different shapes. When the angle needs to be adjusted, the second electromagnet 15 is energized to attract the third slide rail 12, so that the first clamping member 3 and the second clamping member 4 are rigidly connected and can rotate as a whole. This rotation does not require the clamped irregularly shaped clamping plate to be subjected to excessive force. In this way, when each of the two clamping members clamps an irregularly shaped automotive connecting plate for merging and welding, it can avoid the already welded irregularly shaped automotive connecting plate from cracking at the weld due to excessive force. Through the above design, the overall angle of the irregularly shaped connecting plate can be adjusted to meet the angle requirements of different welding parts.

[0032] In use, according to the shape and size of the irregularly shaped car connecting plate, first de-energize the first electromagnet 7, the second electromagnet 15, and the third electromagnet 16. Then, push the slide block 6 along the second slide rail 11 using the adjusting handle 10. Adjust the positions of the first clamping member 3 and the second clamping member 4 on the upright frame 2. Move the sliding block 8 along the first slide rail 5 to adjust the lateral position of the gripper mechanism. Activate the drive cylinder 14 to drive the pneumatic gripper 13 to extend and retract. Adjust its extension distance so that the pneumatic gripper 13 is aligned with the part of the irregularly shaped connecting plate to be clamped. Control the movement of the pneumatic gripper 13 to clamp the irregularly shaped connecting plate. After clamping, energize the first electromagnet 7 and the third electromagnet 16. The first electromagnet 7 attracts and fixes the first slide rail 5. At position 8, the third electromagnet 16 attracts the frame 2 and fixes the slide block 6 to prevent the pneumatic gripper 13 and the slide block 6 from moving. When it is necessary to adjust the welding angle of the irregular connecting plate, the second electromagnet 15 is energized to attract the third slide rail 12, realizing the rigid connection between the first clamping member 3 and the second clamping member 4. At this time, rotating the first clamping member 3 or the second clamping member 4 will drive the two to rotate along the second slide rail 11, adjusting the overall angle of the irregular connecting plate to meet the welding requirements of different sides and angles. During the welding process, the above angle adjustment steps are repeated according to the changes in the welding part until all welding work is completed. After the welding is completed, the pneumatic gripper 13 is released and the connecting plate can be removed.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
